Is the airpressure outside same as inside the room?

Question

I made an experiment that involves measuring the volume of the gas formed but I forgot to write down the temperature and the air pressure.The temperature in the room is nearly always the same but the airpressure I can only guess by the meteorology data for the day.So I'm wondering if the pressure outside for that time of day was 1026hPa then could it have been significantly different in the lab room which is not airthight sealed and is 2 storeys off the ground.

Answer 1

The pressure will be the same both inside and outside the room provided the pressure is taken at the same height from the mean sea level and the room is not airtight.Even if the pressure is taken inside the same room ,one near the ceiling and another near the room floor ,both may slightly differ as the pressure varies by one millibar(hpa) for every 30 feet height ,approximately.On a particular day if the pressure gradient is very steep near the particular room, the pressure taken outside the room at a place one or two hundred yards away, may also slightly vary with that taken inside the room even though the height is the same.

Answer 2

No, the pressure inside and outside will be equal. Obviously if the pressure reading for outside was taken at a different height or a long way from the room location there might be slight differences.

Answer 3

At the same ground level, inside-outside pressures would most likely be equal because the movement of the air. But lower ground level would have a lower atmospheric pressure than higher floor level, i guess.

Answer 4

No significant distinction. some particular rooms would have helpful stress to make optimistic no longer something like undesirable debris receives in, or unfavourable stress to maintain undesirable germs from getting out, yet this is uncommon, and purely a small distinction besides. an significant distinction would make your ears pop once you pass in or out. Even greater desirable adjustments would desire to kill you.
